Selecting CPU MODEL from .bochsrc automatically chooses real HW CPUID and also configures Bochs emulator to emulate this specific CPU including all its features only.
Supported CPUs to choose from:
core2_extreme_x9770
corei7_sandy_bridge_2600K
p4_prescott_celeron_336

Desription for CHANGES:
- Memory
- Added new configure option which enables RAM file backing for large guest
memory with a smaller amount host memory, without causing a panic when
host memory is exhausted (patch by Gary Cameron). To enable configure with
--enable-large-ramfile option.
* moved runtime handlers for cdrom from config.cc to the device object
* cd media status variable is now always of type bx_bool
* changed obsolete gui names like "cdromD" to "cdrom1"
* TODO: implement new runtime config mechanism similar to USB
each other. Devices can register a handler to update it's state after runtime
configuration. The new method update_runtime_options() executes all registered
device handlers before the simulation continues.
- USB host controllers now using the new mechanism to handle the runtime device
change (replaces the previous timer-based implementation). TODO: floppy and
cdrom could use this feature, too)
- improved USB device change messages
* ported the read part of the Qemu vvfat block driver
* added win32 specific directory functions (required for MSVC)
* TODO: write support, FAT32 support, read MBR and boot sector from file
- siminterface: added helper method hdimage_get_mode()
- moved hdimage related stuff from harddrv.cc to the hdimage code
- changed hdimage related names
the default Bochs method using the CTRL key and the middle mouse button there
are now the choices CTRL+F10 (like DOSBox) and CTRL+ALT (like QEMU).
* currently implemented in the X11 and SDL guis only
* TODO: porting to wxWidgets and Win32, documentation updates
to access non-static devices from static parameter handlers.
- removed USB hub register mechanism and use the new device pointer parameter
methods instead
* removed old win32 runtime config dialog since the property sheet isn't
compatible with the win32 ParamDialog
* reorganized runtime parameter lists (usb and cdrom setup in device init)
* renamed win32 StartMenuDialog() to MainMenuDialog() and some related name
changes
* added runtime support to the MainMenuDialog
- win32 start/runtime menu: set keyboard focus to the start/continue button
- win32paramdlg: SetParamList() now checks for list size changes to avoid crash
and value must be != "none" to enable dependents)
- set dependent list for floppy path (removed enable handler)
- win32paramdlg: added support for string parameter dependent lists
non-empty path

- runtime dialog for the first cdrom drive on win32 is now created as a win32
ParamDialog (removed old cdrom1 dialog stuff)
- minor fixes in x11 string dialog for the cdrom path & status case
dependency list processing, enum parameter support)
- bx_param_enum_c: added argument for the default value of the dependent bitmaps
to set_dependent_list()
- bx_param_num_c: dependent_list is now a protected member of the object to make
it accessible for the enum specific dependency code
- config.cc: ata parameter dependency rewrite to avoid multiple dependencies
- config.cc: added missing dependency for SB16 parameter list
Bit64u value with the "enable bitmap" (e. g. bit #0 is the enable value for
the first item of the dependent list). TODO: use this feature in win32 and wx
dialogs
- ata drive type and loader hack parameters now using the enum dependent list
- avoid multiple dependencies in the SB16 config menu
- added file extension support for bx_param_filname_c
- fixed showing of tab control child lists
- added special disk menu for the win32 ParamDialog
- on win32 use the ParamDialog instead of textconfig submenus (TODO: gui dialog
replacement for the start menus
* USB runtime options moved to a new dynamic menu
* USB host controllers create own submenus in init()
* USB runtime parameter handlers simplified
* TODO: related changes in the wx and win32dialog code
* 'usb_uhci' bochsrc option replaces 'usb1'
* minor changes in the USB code
* removed old VBE i/o port registration (they were incompatible with USB)
* updated FSF address
- fixed saving user plugin options
* initialize plugin system before parsing bochsrc and command line
* pass previous value to bx_param_string_c handler
* load / unload plugin in bx_param_string_handler()
* handle user plugins after optional ones in plugin device init, reset and
save/restore functions
* added new siminterface method unregister_user_option()
* removed first version of config option handling for user plugins
* added new parameter subtree for user-defined options
* added new bx_list_c method remove()
* removed unused bx_devmodel_c method init_mem()
Make save/restore default feature, the configure option for save/restore removed from configure script and save/restore made available forever. All code now assume it is exists. Bochs save/restore tree previosly called "save_restore" renamed to "bochs" tree and it will be havily used everywhere, starting from save/restore and ending by various bochs debugger functions. I am going to rework debugger code to get rid of debug CPU access functions and use this "bochs" param tree instead
- removed obsolete structures and members from the USB code
- removed mouse type 'usb' (USB mouse and tablet override selected mouse type
when connected)
- user doc: mention vmware 4 disk image support
string. This is better for devices that need to know all it's options when
connecting to the port. Device name and option should be separated with a
colon. The USB device 'disk' now uses this format ('disk:usbdisk.img).
- the pciusb plugin must be linked with cdrom.o
- new display library option "windebug" enables the new feature
- simple dialog box with a command line and a multiline text viever
- TODO: implement modeless dialog with cpu registers and it should be possible
to interrupt "continue" and "step N" commands
- win32dialog: fixed function GetBochsWindow()
- textconfig: removed unused save/restore prompt
changed after initializing the config interface
- PARAM_TREE.txt updated and cleaned up (TODO: improve developer documentation
and get rid of this file)
* don't initialize cpu specific parameters for the wx debugger if they already
exist

* old wxWidgets save state code removed (not thread-safe)
- wxWidgets HandleAskParamString() method fixed for wxGTK (now using a temporary
string array instead of a pointer)
* changed data format of text files for save/restore (looks like C/C++ structures,
similar to the format used in old save/restore branches)
* don't set the initial value of shadow bool parameters
* don't set the initial value of bool parameters twice
* cpu/init.cc: missing #undef added
* ne2k.cc: variable tx_timer_active was never set to 1 (type now bx_bool)
* floppy.cc: missing initialization of the 'eot' array in reset() added
* pic.h: type of member 'byte_expected' changed to Bit8u
* pit_wrap.h: unused members removed
* fixed minimum limit of signed variable types
* don't set the initial value of shadow parameters
* fixed range check for shadow parameters
* added support for setting the value base (decimal/hex) of numeric shadow parameters.
The text format hex number is now initialized in the constructor
* added missing newline after filename for binary data
* fixed data size of 64-bit shadow parameters
* fixed save/restore output format of numeric parameters (signed/unsigned/64-bit)
* cpu/init.cc: fixed macro name and added missing #undef line
* new parameter object type bx_shadow_data_c for binary arrays (e.g. system
and video memory, CMOS RAM, PCI config space)
* save_state() completed and restore_hardware() implemented
* get_sr_root() returns the list with the save/restore subtree
- for the BrowseDir() function Bochs for win32 needs to be linked with SHELL32.DLL
(currently used for the save/restore support only)
- save/restore support symbol name changed
- don't load another config file if the restore flag is set
- disabled restore_hardware() for now (will be enabled when save/restore is
complete and stable)
parameters of the wx debugger possible

- removed unnecessary spaces
- parameter tree structure updated (TODO: should be moved to development.dbk)
- code cleanup: bx_options stuff and obsolete parameter access methods removed
- TODO: rewrite of shadow parameter stuff (for subtree "save_restore")
- sb16 parameters stored in the device class and runtime parameter handler added
- wx: ParamDialog can currently handle only dependency lists of bool parameters
correctly (TODO: add support for numeric parameters)
- disable usb options if not compiled with usb support
- usb and network dependency list created with menu->clone()
- load usb plugin only if at least one hub is present
